云南松根系对土壤牵引效应测试系统的设计与实现

Design and Realization of the Test System on Mechanical Effect of Yunnan Pine Root and Soil

目前在野外对云南松根系与土壤的机械效应的研究 ,由于测试研究受多种因数的影响 ,开展研究困难较大 ,研究精度也受到一定程度的影响 ,这对较深入的描述根系与土壤相互作用的机械效应带来一定的困难 .。本文基于这一实际 ,设计了能在室内和野外进行实时测试分析的测试系统 ,并配套了支持PCMCIA插槽的DAQP - 12型模数转换 (A/D)卡 ,以及直流电供电的QT - 30 0型调理装置。结合所配套的硬件 ,利用VisualC在Windows95 / 98平台编写了软件 ,经过实际试验测试 。

The research of mechanical effect on Yunnan pine root and soil at field presently, owing to been influence of multi-factor on test and research. It is more difficulty to be researching. The precision of study has been influence of extent to a certainly. It is more difficulty to describe in-depth mechanical effect on Yunnan pine root and soil. This paper is based upon the fact. We designed a test system which can test data at real time on room and field, and it's correspond to hold out PCMCIA stick of A/D conversion block ,and suit well device QT-300 by DC power supply. Windows 95/98's application software has been compiled by Visual C to combine with hardware. The system has been tested variedly, its capability can meet the need of test and analysis for mechanical effect on root and soil.
